Using the technique of impedance spectroscopy, data on effect magnitude variable signal and constant bias kinetic characteristics Ag x MoSe 2 samples were obtained. The temperature parameters spectra studied compounds their dielectric characteristics, which analyzed within framework electrical modulus formalism, is also shown. Keywords: impedance, intercalates, molybdenum diselenide, silver, pe...

In the microcrystalline regime, the behavior of grain boundary-controlled electroceramics is well described by the “brick layer model” (BLM). In the nanocrystalline regime, however, grain boundary layers can represent a significant volume fraction of the overall microstructure and simple layer models are no longer valid. This work describes the development of a pixel-based finite-difference app...

The efficacy of emerging microwave breast cancer detection and treatment techniques will depend, in part, on the dielectric properties of normal breast tissue. However, knowledge of these properties at microwave frequencies has been limited due to gaps and discrepancies in previously reported small-scale studies. To address these issues, we experimentally characterized the wideband microwave-fr...

Electrical impedance spectroscopy (EIS) is a noninvasive method for characterizing the dielectric properties of biological particles. The technique can differentiate between cell types and provide information on cell properties through measurement of the permittivity and conductivity of the cell membrane and cytoplasm. In terms of lab-on-a-chip (LOC) technology, cells pass sequentially through ...

Local electrochemical impedance spectroscopy (LEIS), which provides a powerful tool for exploration of electrode heterogeneity, has its roots in the development of electrochemical techniques employing scanning of microelectrodes. The historical development of local impedance spectroscopy measurements is reviewed, and guidelines are presented for implementation of LEIS. The factors which control...

Abstrac t Electroporation or electropermeabilization is a phenomenon observed when lipid bilayers, generally cell membranes, are exposed to high electric field pulses becoming transiently permeable to molecules that under regular conditions are not able to penetrate through them. This change in molecular permeability is believed to be produced by transient aqueous pores created in the lipidic s...

The adsorption of heavy metals (Pb and Ni) in raw Wyoming bentonite was investigated by means of broadband dielectric spectroscopy (BDS) in the frequency range 10 -2 Hz – 10 6 Hz and at elevated temperatures, up to 1000 o C. In order to reveal various aspects of data interpretation, different formalisms of analysis were investigated, namely, complex electrical conductivity, dielectric modulus a...
